A study to investigate the impact of requirements instability on software defects

摘要: Software development is a dynamic process and characterized by change. projects often begin with unclear, ambiguous, incomplete requirements which give rise to intrinsic volatility. Constant change in one of the main causes software defects major issue faced industry. This paper describes findings our research-based study that investigates impact both pre-release post-release changes on overall defining measures, collecting data against those measures analyzing collected through statistical techniques. Our findings, based industry from 4 consisting 30 releases, all e-commerce domain, indicate there significant relationship between pre/post release requests initiated client defects. In addition, analysis indicates design system at later stages i.e., during coding, testing after have high severity affect functionality system. Also, we found insufficient time spent phase inadequate communication could be some consequently
